That is what I did to get two integrals.
omarsubei:
Ya I looked at that. I don't understand their method, but I can see that in your method, you put the same equation twice, you need to put one of them as +square root... and the other as -square root..., if you see what I mean
omarsubei:
I don' get how you went from step one to two, how'd you put the integrals together?
astarmathsandphysics:
You are right. I corrected my mistake.

Exapnad the brackets and simplify. You can just add the integrands. The squared terms cancel and for one term I get--=+
